which will conclude the moderniza-

New production standards meant
that we no longer had sufficient
capacities for quality assurance and
development at our Plant II; accor-
dingly, a new laboratory extruder
was purchased in the past weeks.

Since both our production and stora-
ge capacities more than reached
their limits last year, Müller Kunst-

and production hall as an extension
to Plant II. The investment volume for
the 3,000 sqm reinforced concrete
building will be in the region of
EUR 1.2 million and the new equip-

truder line at the end of 2004, which
will require a further EUR 1.2 million.
